The taping device I Ilincludes a rotatably'driven' shuttleI I2extendinga-round and mounted in a grooved annular bearing I 3; Saidbearing isA 0'1"r 1 a substantially C-shaped formation with an openportion MQ tol permit an armature coil I 1`LA to be inserted -in theopencenterthereof.y Saidy shutg" tle is' likewise of a C-shaped`Vformation'`1 ari-dis" provided withy an openportion- I5, to permit saidiarmaturey coiltov be inserted therethrough land` said shuttle.

arev disposed at. thepf'orward endV of said frame,

x mounted' at the opposite vend of said frame on a. horizontal shaft222'. l.Said shaft and pulley are driven Yfrom a motor 23., mounted onsaid plate, through a exible couplingZlI.

I A tension A15111195? 7216; mounted Ori. vanadjustably movable arim 2T, engages thev outer-side of' the upper run fthe belt' 2,5`, for' maintaining said beltl atI the desired tension., ,ny

A s" Vol' orbobbin 29' is mounted onthe shuttle IZffor rotationtherewith on a pin r3l). .Said bobbinis'adapted to pay'oif a'tape 3l",woundthereon; Said tp is` threaded from said bobbn bef tweenja tensionspring 32' anda tension'plate 33, andinwardlyfromsaid tension platetothe armature coil; whereitiswound thereon by rotation off saidshuttle' andbottin with respect to the coilQ-in a direction which inFigure 1 shown as' being 'a clockwise direction.y A shouldered glid'e'35` is; provided in the' Central portion of'thh shuttle and; the-,othermoving away from sarai shuttle* during" the' winding operation. Each ofsani-hand rests has a fiat-upper portion 3i to" forni 'a rest l for Ithel'hand and has .an upwardly spaced shouldered portion 39, againstwhich the ation. The harid'restsv 35,536', as herein shown, are' eachmounted ori the'upper ed of a` separate upright leg 40, whichlis'krount'ed andr projectsju'pwardly from' an internallythreaded sectorof' a sleevel, forming a partial'nut engageablel with; the threads' of'a rct'atamy driven- `threac'ied shaft 443. Said legs extend through andare guided in guides 44, 44 formed in the top plate I9 and extendingalong said plate in a direction parallel to the axis of rotation of theshuttle I2.

The partial nut 4I is herein shown as being substantially a third of anut so that during rotation of the threaded shaft 43, when there is noweight on the hand rest 36, the threads of said sleeve will come out of`mesh of the threads of said threaded shaft and said nut will remainstationary. When, however, the weight of the hand is placed on said handrest, the threads of said nut will be engaged with the threads of saidthreaded shaft to cause said nut and hand rest to travel along saidshaft, upon rotation thereof. Said hand rests may be connected in fixedspaced relation with respect to each other by means of a tie rod 42.Said tie rod may however be dispensed with where the lengths of thecoils being taped differ, or where it is necessary to frequently adjustthe spacing between the hand rests for different operators.

The drive from the motor 23 to the threaded shaft 43 includes a ipulley45 on an end of a shaft 46. Said shaft is journaled intermediate itsends in a bracket 48 projecting from the frame I8, and has the lowerpulley 26 secured to its end opposite said pulley 45, which serves todrive said shaft and said pulley 45. The pulley 45 is connected with apulley 41 on a parallel shaft 49 by means of a drive belt 56. Saidparallel shaft is journaled at its ends in a gear housing I, secured tothe end of the plate I9 and forming a guard for change speed gearing fordriving the threaded shaft 43 from the shaft 49 at a plurality ofpredetermined speeds.

Three gears 53, 54 and 55 are herein shown asl being cut integral withthe parallel shaft 49. Either one of said gears is adapted to mesh witha gear 56 journaled on a shaft 51, which is mounted at its ends in ayoke 58 journaled on a hub In operation of the machine, the gear 56 ismeshed with either of the gears 53, 54 or 55, depending upon the desiredlap of the tape. The armature coil is then inserted through the openportion of the frame I8 and the open portions I4 and I5 of the shuttleI2 and bearing I3 respectively. The vertical edge of said armature coilis then engaged with the shouldered guide 35 and the shouldered guides39, 39, said coil then being in a position so that the portion to betaped extends in the direction of the axis of rotation of the shuttle.The rnotor 23 is then started, the hands holding the coil in engage- 59of a spur gear 66, on opposite sides of said gear. Said last mentionedspur gear extends within said yoke and is feathered on the shaft 43 formovement therealong, and is also meshed with and driven from the spurgear 56, which is journaled in said yoke.

Rectilinear movement of the yoke 58 and spur gear 60 along the shaft 43will thus position the spur gear 56 to mesh with either one of the spurgears 53, 54 or 55, so the threaded shaft 43 may be driven at aplurality of predetermined speeds. Said yoke and spur gear are movedalong said shaft by means of a hand lever 6I extending outwardlytherefrom through a slot 62 forfmed in an end wall 63 of said gearhousing. The upper portion of said slot is of a stepped formation topermit said yoke to be moved to a position to mesh the gear 56 witheither of the gears 53, 54 or 55, or to permit said gear 56 to be movedout of mesh from all of said gears.

The means for locking the gear 56 in mesh with either of the gears 53,54 or 55 is herein shown as being a spin and aperture lock including aplunger 64 slidably mounted in an upwardly projecting bracket 65 of thehand lever 6I. A spring 66 encircles said plunger and abuts the innerside of said bracket at one of its ends and a pin 61 at its oppositeend. Said pin is mounted `in and extends through the plunger 64, so thatwhen it is engaged by said spring said plunger will be urged in adirection to engage either one of a plurality of apertures 68, 69 or 16,corresponding with the positions when said gear 56 is isn5 mesh witheither one of the gears 5354 or ment with the shouldered guides 39, 39and resting on the hand rests 36, 36, to engage the secvtors'or partial.nuts 4I, 4I with the threads of the threaded shaft 43, so said shaftwill move said hand rests with respect tosaid shuttle at a predeterminedspeed in the direction of the axis of rotation thereof.

Where it is desired that the leads or the legs of the coil be taped witha greater lap than the `slot portions thereof, the speed of rotation ofthe threaded shaft 43 is changed by meshing the gear 56 with the desiredgear 53, 54 or 55. It should here be understood that while onlythreegears are herein shown, any number 0f gears may be provided which may bemeshed with the gear 56 to provide the required feed of the armaturecoil, to give the desired lap of the tape thereon.

When it is desired to tape the knuckle of the coil, the hands areremoved from the hand rests to stop rectilinear movement thereof and thecoil may be turned `by hand to correspond to the intricate curve of theknuckle. When taping of the knuckle is completed, the hands may again beplaced on said hand rests to tape the remainder of the coil lwith thedesired lap.

While I have herein shown and described one form in which my inventionmay be embodied, it will be understood that the construction thereof andthe arrangement of the various parts may be altered without departingfrom the spirit and scope thereof. Furthermore, I do not wish to beconstrued as limiting my invention to the specific embodiment-lllustrated, excepting as it -may be limited in the appended claims.
